movable for refilling with abrasive or polishing material. 1 A further object of this invention is to provide a surfacing machine, operated by flexible shafting, compactly arranged and easily carried about.

vVith these and other objects in view, the

2 invention consists in certain novel features of construction as hereinafter shown and described, and then specifically pointed out in theclaims, and in the drawings illustrative of the preferred embodiment of the invention.

In the accompanying drawings:

Figure 1 is a plain view of the device.

Figure 2 is a side view of the device.

Figure 3 is a view taken on 33 Figure 1.

Figure 4 is a detail of the surfacing ma- 30 terial.

Figure 5 is a side view of the device with a box and handle.

In the drawings, numerals refer to similar parts of the drawings.

The improved device, comprises a supporting frame 10, which includes spaced longitudinal rods 11 and 12, connected by a rod 13.

Upon the rods 11 and 12, a flat member 14 is adapted to slide longitudinally.

The flat member 14, is stamped out of metal, and comprises end portions 15 and 16.

The flat member 14 is provided with a projection 19. At the end of the-projection, a link 20 is revolvably connected to the projection by means of a pin 21. At the other end of the link 20 another pin 22 is set, its function to be described later.

The motive power for the device is obtained through a flexible shaft 23, within a tube 24. On a plate 25, two collars-26 and 27 are a worm gear 28. This worm gear is fastened PATENT fastened. Betweenfthese collars there is set tothe shaft 29 which is the continuation ofthe flexible shaft 23 and rests in the collars'as' bearings.

V I k p The method of fasteningthe worm gear28 .to the shaft 29, is merely by flattening lthe shaft 29 at 30 and providing an opening in the worm gear with a'similar flat side soas to prevent rotation on the shaft 29.

The shaft 29 extends and passes adown- Lyard projection 31 depending from the memer 14. i

A collar 32 is fitted on the shaft 33. A spur gear 34 is welded or otherwise attached to the collar 32.

Both collar 32,'the'spur gear34 are adaptedto move up and downthe shaft 29.

The shaft extends until'the point 35, where it is rounded and the point 35 rests within a tubular lug 36 on the rod 13. On the plate 25, there is provided a 'double' gear 37 revolving on :a pin 38- Thefdouble gear consists of a'large pinion39, and smnr pinion 40. The'large pinion'is' in mesh with the worm gear 28. v

A. block '41, is provided to which a small" pinion42 is rotatively connected by means of a pin 43.

A "hain' 44 and 42. p

The pin22, mentioned heret'ofore, is connected to one ofthe' links in the chain 44, and is made tosfollowthe coursemade by the chain 44, and due tothe link-20, which ro tates on the pin 21, the turns around the pinions are easily made.

To the block 41 thereis attached by weldi'ng'or otherwise, a vertical bar 45. This bar is attached to the frame rod .11 and is held travels on thetwo 'pinions 40 to by means of'a nut 46.

number of washers 54 are 53 for taking up space. 1

The other end portion 16 is also provided with a block 55 attached to the end portion by means of screws 56 and 57. The block 55 is placed on the axis also provided with opening 58 for sliding on' the frame rod 12.

Into the block 55, there is also screwed'a guide bar 59.' This bar 59 passes through an opening 60in the bar 45. V

The frame member 12 extends through the block 41, and is held thereto by means of the shoulder 61 of the bar 12 and the nut 62at 1 the end of the bar 12. r

The end portion 16 is provided with an extension 63 and a downwardly bent member 64. This member 64 is provided with an aperture 65 in which the axis 66 of the surfacing element is supported.

A bevel gear 67 is attached to the surfacing element and is in mesh with the spur gear 34.

The surfacing element 47 ismade of a cylindrical form and to the surface of the cylinder there is attached the abrasive or polishing material as desired. The abrasive or polishing cloth is attached to the surfacing element so that the meeting edges of the material lie in a diagonal line 68, across, the surfacing element. T 1

In Figure 4, there is illustrated a roll of abrasive or polishing material 72. The numerals 69 and 70 refer tothe dotted lines along which the material 7 2 is to be cut into portions to be attached tothe surfacing elev l ment as shown. The circles 71 indicate pats of cement or glue for attaching the material to the element 47. Any other method of attaching can be used if desired. 7

In Figure 5, the device is shown with th operating means inclosed in a box 7 3, which is carriedby a handle 74, and'attached to said box by means of connections75 and 76. WV hat I claim is:

; In a surfacing machine, a surfacing element having a gear on one side of same, a shaft, a supporting member forsaid element, a spur gear connected to said shaft and meshing with said gear on the element, a worm gear on the shaft, a large' pinion 'meshing with saidworm gear, a small pinion attached to said large pinion, a second pinion set off from the small pinion, a link chain traveling on the last two mentioned pinions,.a link revolvably attached'to said supporting ni'em-f her, a pin in the free end of said link, said.

pin being set in one of the links of said chain and adapted to travel with: said chain for causing forward or backward movement of said element.
